Studies
of Nanoscale Structure and Structural Defects in Advanced Materials:
The
goal of this program is to study property sensitive structural defects
in technologically-important materials such as superconductors, magnets,
and other functional materials at nanoscale. Advanced quantitative electron microscopy techniques, such as
coherent diffraction, atomic imaging, spectroscopy, and phase retrieval
methods including electron holography are developed and employed to
study material behaviors. Computer
simulations and theoretical modeling are carried out to aid the
interpretation of experimental data.

Electron Spectroscopy Groupís primary focus is on the
electronic structure and dynamics of condensed matter systems. The
group carries out studies on a range materials including strongly
correlated systems and thin metallic films. A special emphasis is
placed on studies of high-Tc superconductors and related materials.

X-Ray Scattering Group carry out basic studies of the
structural, electronic and magnetic properties of condensed matter
systems using synchrotron-based x-ray scattering techniques.
Particular emphasis is placed on electronic and magnetic structure and
phase behavior, on electronic excitations in solids and on the
investigation of surface and interfacial phenomena.

Condensed Matter Theory Group conducts basic research over a
wide swath of theoretical physics, ranging from strongly correlated
electrons to first principle electronic structure theory to the
statistical mechanics of complex systems.

Correlated Electrons Group focuses on the properties of
magnetic materials, and in particular on understanding the general
conditions under which magnetic order is stabilized. We are interested
not only on how magnetic moments forms or survive in the metallic
environment, but also in the interplay of moment stability and magnetic
order.

Superconducting
Materials: The research focuses on detailed elucidation and
optimization of the properties of both low-TC superconductors
such as Nb3Sn and high-TC superconducting cuprates
such as YBa2Cu3O7 (YBCO) and the
recently discovered MgB2.Studies include investigations of physical properties and lattice
defects, especially their role in altering superconducting properties,
as well as the kinetics of formation of superconductors in practical
conductors.

Magnetic
Materials: It is the task of this program to study and elucidate
factors that determine the macroscopic magnetic response in nanostructured magnetic materials. The research strategy is to focus on materials factors, both
intrinsic and extrinsic, that provide functionality to magnetic
materials that support selected missions of the DOE.

One of ten national laboratories overseen and primarily funded by the Office of
Science of the U.S. Department of Energy (DOE), Brookhaven National Laboratory
conducts research in the physical, biomedical, and environmental sciences, as
well as in energy technologies and national security. Brookhaven Lab also builds
and operates major scientific facilities available to university, industry and
government researchers. Brookhaven is operated and managed for DOE's Office of
Science by Brookhaven Science Associates, a limited-liability company founded by
the Research Foundation for the State University of New York on behalf of Stony
Brook University, the largest academic user of Laboratory facilities, and Battelle,
a nonprofit, applied science and technology organization.
